Differential Pressure Balancing Valve
Differential Pressure Balancing Valve (DN40-DN250)
Application:
The Differential Pressure Balancing Valve is designed to keep constant differential pressure across the supply pipes and return pipes, control valve or terminal unit in air-conditioning or heating system. It avoids hydronic disturbances resulting from variations 1n system differential pressure
Features:
Self-acting differential pressure control, no external power needed
On-site setting of differential pressure
Wide controllable range of differential pressure
Handwheel equipped with differential pressure indicator
Equipped with measuring points and air vent
Equipped with three-way measuring connector
Operating principles:
When the network's differential pressure increases, the Differential Pressure Balancing Valve will diminish its opening automatically. This counteracts the increased value, ensuring constant differential pressure

Working Range:
Installation:
The Differential Pressure Balancing Valve can work with a Static Balancing Valve or work alone The static balancing valve with flowing arrow point 1n the direction of the flow You must washthe pipesafter installation and put it installed on the front of strainer. Capillary type pipes should be connected to the water supply piping or above level, but not in below the pipe, to prevent dust particle. You must install the capillary type signal tube and connect with rotating block valve before test Otherwise, the pressure differential regulator will be damaged by the pressure When combined with a Static Balancing Valve, it should be installed on the return pipe, while the Static Balancing Valve should be installed on the supply pipe
